Sports spread betting is when the odds for a given sporting event will be determined on the very night when the bets are placed . The goal is to adjust event odds to 50/50 chance of winning , so a casino or bookmaker only pay out 50% of their players . For example, if a strong basketball team will be playing against a sub- tipped opponent , the majority of sports bet players choose to focus on the strong team ( " favorites " ) will win. The odds of the strong team will win will be much higher than for the underdog team ( "underdog "). Point - spread in sports spread betting allows you to adjust the two odds are equal

This is achieved by " favorites " to live up to a winning claims by winning a certain number of points above the "underdog " . If " favorites " do not win with the specified number of points , the sports bet players who have bet on " favorites " , not win. Therefore, there will be sports bet players who believe that " favorites " will win, but not with the required number of winning points, and they will therefore focus on the " underdog " instead.

Based on the number of events that are received prior to the match , the point spread changes. For example, if the " favorites " to win by 7 points over the " underdog " and sports bet players continue to wager that " favorites " wins over "underdog ", the requirement for the number of points the favorite team to win in it to win gap increases. Winner requirement , for example up to 10 points.
